Janitors from schools across Glasgow will walk out next week as part of a week-long strike.

The action follows shorter staged strikes in March and April, and members of Unison continue to boycott certain duties amid a pay dispute.

The janitors say they deserve more money for dirty jobs or heavy lifting, and the union has said that they should be entitled to a Working Context and Demands Payment- ranging from £500 to £1,000 annually.

The action will only involve those who work in Glasgow primary schools, and who are members of Unison.

A spokeswoman for Glasgow City Council said that all schools and nurseries will be open as usual, adding: “Our expectation is that all breakfast clubs will operate as normal during the five-day industrial action.

“However, parents and carers need to be aware that this is subject to change at short notice depending on local arrangements and circumstances.”
